I have been trying to typeset text onto curves and have been successful with the help of the MetaFun manual, and the followtext command which I saw in some correspondence between dr Hans van der Meer and Hans Hagen on the mailing list in January this year ( the subject was Double Follow Tokens).
The followtext command seems to used for a simple line of text and if I increase the number of words in the line the font size is reduced to make it fit to the length of the curve (see MWE below). I would like to typeset complete paragraphs on the curve(s) and the only way I see of doing this without the font size changing is to manually create each line separately.
Is their a way where this can be done by MetaFun automatically rather than manually? It would be really nice if I could create a number of curves and then MetaFun typsets a paragraph of text on to them. Also, can other options be used with followtext e.g. \input file?
I'm a complete novice with MetaFun so any advice appreciated.
Best Wishes

----Minimum Working Example----
\starttext
Two different lengths of text on the same curve showing font size being reduced.
\blank
\startMPcode
path q; q := function (1, "x", "sin(2x)" , 1, 10, .01) scaled 1.5cm ;
draw followtext(q, "some text but not that long. But here and there and everywhere the text can become longer");
draw followtext (q shifted (0cm,-2cm), "some text but not that long. But here and there and everywhere the text can become longer and longer and longer finally ending here.");
\stopMPcode
Some other examples of text on a curve\blank
\startMPcode
path p; p := reverse halfcircle xyscaled 55mm ;
draw followtext(p, "some text but not that long");
\stopMPcode
nice spiral shape with text
\startMPcode
z0 = (0,0); z1 = (60,40);
z2 = (40,90); z3 = (10,70);
z4 = (30,50);
path p; p = (z0..z1..z2..z3..z4) ;
draw followtext(p scaled 1mm, "some text but not that long. But here and there and everywhere the text can become longer");
\stopMPcode
